IMPROVEMENT IN VEHICLE-SPRINGS.

Specifieation forming part 0f Letters Patent N0. 213,748, dated April 1, 1879; application filed August 16, 1878.

T0 all whom it mag; concern:

Be it known that I, ALBERT GUMMER, of Omro, Winnebago county, Wisconsin, have invented eertain Improvements in Vehicle- Springs, 0f which the following is a specification:

'lbe natura of my invention relates t0 the use, in a vehicle-spring, of a forked stud supporting a circular bearing, and an elastic saddle, to prevent severe concussion of the parts coming tog6ther under a load, and also a staychain 01' band t0 prevenl: the rebound.

Figure 1 is a section 0f the deviee on the line c d. Fig. 2 is a p1an, am]. Fig. 3 is a section on a b.

A is the upper half of the spring, and B the lower half, joined ab the ends by apin, D, .and slot; C. E is a forked stud 01 simple within 01 under the spring, the ears of which furnish bearings for an elastic circular bearing, F, in which an elongated 01 a wund. hole is made in the center, so that it may rast either 011 the center-pin X, 01 011 the bottom of the fork of the stud E. In the 1atter ease the pin L, 01' its equivalent, enters the bearing to keep it from turning around. Under and around this bearing passes the eord. 01 band I, attaehed 110 the upper half of the spring by a plante, G. This is to prevent too great a rebound 0f the vehicle-body.

J is a similar band, fastened to the forked stud. and upp'er half 0f the spring. Either 01 both 0f these bands, 01 their equivalent-s, may be used.

H is an elastic saddle, which meets the circular bearing F when under pressure.

I claim- A In a vehicle-spring, A B, the combination of the forked stud E, the cylindrical bearing F, the glastic saddles H, am]. stay-band I o1 J, substantially as shown and deseribed.

ALBERT GUMMER.
